Notes

20.

V2 specification with external capacitor. Stability requirement: capacitance > 42

μF and ESR < 1.3Ω (tantalum capacitor), external

resistor between base and emitter required. Measurement conditions: ballast transistor MJD32C, capacitance > 10

μF tantalum, 2.2kΩ

resistor between base and emitter of ballast transistor.

21.

The guaranteed V2CTRL current capability is 10mA. No active current limiting is used so the actual available current may be higher.

22.

Push-pull structure with tri-state condition (CS HIGH).

Table 5. Static Electrical Characteristics (continued)

Characteristics noted under conditions 4.75V

≤ V2 ≤ 5.25V, 5.5V ≤ VSUP ≤ 18V, and -40°C ≤ TA ≤ 125°C. Typical values noted

reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted.
